The removal of impacted mandibular third molar is a common surgical procedure entailing some risk of complications, especially when the tooth and the inferior alveolar nerve and/or lingual cortical plate are in close proximity. A technique that can reduce the possibility of damage is the Ultra Sonic Bone Surgery. The aim of this report is to present a paradigmatic case of an impacted mandibular...

Problem statement: The traditional approaches in mobile robot research are the use of stereo vision systems to extract range information from pairs of images. One of the difficulties of techniques in navigation is that the intrinsic computational expense of extracting three dimensional information from stereo pairs of images. Approach: To compare performance sensor readings from environment bet...

Introduction Flow weighted gradient echo MRI techniques can be used for angiography. Furthermore, these techniques allow to visualise the ventilation of aquatic animals (1). Therefore using MRI, it should be possible to observe ventilation and blood flow in marine animals at the same time. Biochemical investigations led to the hypothesis that thermal tolerance is limited by insufficient oxygen ...

Lai et al. concluded that Ultra Sonic-guided synovial SuperCore biopsy instrument is a fruitful method to conduct synovial research [1]. They discussed the advantages of simple, micro invasiveness that correlates well with a relatively high rate of success. They further continued that the complications due to biopsy methodologies are rare. Authors were optimistic about future refinements of thi...

Many manipulation systems using air flow have been proposed for object handling in a non-prehensile way and without solid-to-solid contact. Potential applications include high-speed transport of fragile and clean products and high-resolution positioning of wafers. This paper discusses a comprehensive survey of state-of-the art pneumatic manipulation from the macro scale to the micro scale. The ...

Every year, several environmental causes let significant amounts of grain spoil even though it is properly stored in dedicated silos. To reduces the resulting financial losses, engineers have developed a special robot called grainbutler. The robot is supposed to cover the entire area in a systematic way. To this end, a PC-based control software derives the robot’s current position and submitts ...

The propagation dynamics of the nucleus-acoustic waves (NAW) in a quantum plasma composed nondegenerate inertial light nuclei, stationary heavy and ultra-relativistically degenerate electrons positrons has been theoretically investigated within framework Boussinesq equation, which is valid for bi-directional small but finite amplitude limit. N-soliton solution equation derived using Hirota's me...
